Plaza Theater

I remember “Story of Ruth” and “Rio Conchos” at the Casa Linda in Dallas, early 60’s. Although you might think they would appeal to totally different audiences (Biblical story vs Western), both were Stuart Whitman vehicles and both were Twentieth Century-Fox pictures. Oftentimes, the packaging was done by the distributors' zone offices and depended on what they could get their hands on (or had lying around waiting for shipment back to the home office) that they could rent out for a week and turn a buck on while they waited for enough other in-use titles to be returned to make a shipment worthwhile from a cost perspective.

A weepy alcoholic biopic and a Western seem a little at odds.

That was a double feature in 1955? Those two films would be unlikely to attract the same audience.
